INTRODUCTION
The Mercedes-Benz GLE 350d 4MATIC G-TRONIC, launched in 2019 as part of the V167 GLE generation, was a diesel-powered variant of the popular mid-size luxury SUV. The V167 represented a significant step forward for the GLE, moving it onto the MHA (Modular High Architecture) platform shared with other Mercedes-Benz models. This platform allowed for greater flexibility in powertrain options and interior packaging. The 350d trim specifically targeted buyers who prioritized fuel efficiency and torque, offering a compelling alternative to the gasoline-powered GLE variants. It was positioned as a mid-range offering, slotting between the entry-level GLE 300d and the higher-performance GLE 450.
Powertrain & Engine Architecture
At the heart of the GLE 350d 4MATIC lies the OM 656.929, a 2.9-liter inline-six cylinder diesel engine. This engine is a cornerstone of Mercedes-Benz’s modern diesel strategy, known for its refined operation and strong performance. The OM 656 features a sophisticated diesel commonrail injection system, delivering fuel at extremely high pressures for optimized combustion. A single-stage turbocharger with variable geometry turbine (VGT) and an intercooler further enhance power and efficiency. The engine also incorporates a close-coupled Diesel Particulate Filter (DPF) to minimize emissions, meeting stringent Euro 6d ISC-FCM standards. Paired with the engine is the 9G-TRONIC nine-speed automatic transmission, renowned for its smooth shifts and wide gear ratio spread. This transmission is designed to optimize fuel economy and provide responsive acceleration. The 9G-TRONIC features a torque converter lockup clutch that engages in most driving situations, reducing parasitic losses and improving efficiency.
Driving Characteristics
The GLE 350d 4MATIC delivers a driving experience characterized by strong low-end torque and smooth, effortless cruising. The 600 Nm (442.54 lb.-ft.) of torque available from just 1200 rpm provides ample power for overtaking and accelerating from a standstill. While not as overtly sporty as the gasoline-powered GLE 450, the 350d offers a more than adequate 0-60 mph time of around 6.3 seconds. The 9G-TRONIC transmission contributes to a relaxed driving experience, with well-spaced gear ratios that keep the engine in its optimal power band. The 4MATIC all-wheel-drive system provides excellent traction in various conditions, enhancing stability and confidence. The suspension, tuned for comfort, absorbs bumps and imperfections in the road effectively, providing a refined ride quality. Compared to manual transmission versions (not commonly available in this configuration), the 9G-TRONIC prioritizes ease of use and fuel efficiency over outright driver engagement.
Equipment & Trim Levels
The GLE 350d 4MATIC typically came well-equipped as standard. Interior features included premium upholstery (often MB-Tex or leatherette), power-adjustable front seats with memory function, dual-zone automatic climate control, and the Mercedes-Benz User Experience (MBUX) infotainment system with a large touchscreen display. Standard safety features included adaptive cruise control, lane-keeping assist, automatic emergency braking, and blind-spot monitoring. Optional extras included a panoramic sunroof, premium Burmester sound system, ventilated and massaging front seats, and a variety of interior trim options. The GLE 350d could be further customized with AMG styling packages, adding sporty exterior accents and interior details.
Chassis & Braking
The V167 GLE features a sophisticated chassis design. The front suspension utilizes a four-link independent setup, while the rear employs a multi-link independent suspension. Air suspension was often equipped, providing adjustable ride height and improved comfort. The GLE 350d typically featured ventilated disc brakes on all four wheels, providing ample stopping power. ABS (Anti-lock Braking System) and Electronic Stability Program (ESP) were standard safety features. Steering is rack and pinion with electric power assistance, offering precise and responsive handling. The GLE 350d’s suspension tuning was generally softer than that of the higher-performance GLE variants, prioritizing ride comfort over sporty handling.
Market Reception & Comparison
The GLE 350d 4MATIC was generally well-received by automotive critics. It was praised for its refined engine, comfortable ride, and spacious interior. Fuel economy was a key selling point, with the diesel engine offering significantly better mileage than the gasoline alternatives. Compared to the GLE 300d, the 350d offered a noticeable performance upgrade. Compared to the GLE 450, the 350d prioritized fuel efficiency and torque over outright horsepower. Reliability reports have been generally positive, although diesel engines can be more complex to maintain than gasoline engines, potentially leading to higher repair costs over the long term.
Legacy
The OM 656 engine family, as used in the GLE 350d, has proven to be a robust and reliable powertrain. While diesel engines are facing increasing scrutiny due to emissions concerns, the OM 656 represents a modern diesel design that incorporates advanced technologies to minimize pollutants. On the used car market, the GLE 350d 4MATIC remains a desirable option for buyers seeking a luxurious and fuel-efficient SUV. Its combination of comfort, performance, and practicality ensures its continued appeal for years to come. Proper maintenance, including regular DPF servicing, is crucial to ensure the long-term reliability of this powertrain.
